I'm with Thorne on that - and the idea of "union-only jobs" strikes me as entirely wrong, not to mention illegal in a lot of jurisdictions these days! (Completely prohibited in the UK and Australia, as well as 22 States, Guam and the federal government.)
Certainly not a development I'd object to. I read earlier this week that another side-effect of the new law is that the union-affiliated insurance company has stopped ripping teachers off: since the new law ended their monopoly, they've had to cut premiums down to a competitive level at last.
